Part-Ticular Parts T304 Oxygen Sensor Bung & Plug Set
This Part-Ticular Parts T304 stainless oxygen sensor bung and plug set is built for clean, reliable O₂ sensor installs on custom exhausts and turbo setups. The weld-on bungs give your narrowband or wideband sensor a proper M18 x 1.5 seat, while the matching stainless plugs seal unused ports or let you remove a sensor for tuning without leaving a leak. Perfect for fabricators, dyno shops, and DIY builders who want hardware that won’t rust out after a few winters.
